It may have already been pointed out but the mural in the first page is quite interesting too... Let's see how that plays into matters.
I'm also terribly curious if Terezi's Quirk being cited in one of the instructional prompts is from Terezi being the first guardian of Deltritus and/or acting as a sort of exile for them or it's more a grace note to Ly'Lac having Terezi's tag.
Similarly the question of which tag is the sixth delta player (as I call the Deltritus team) is up in the air still. Tavros' would probably play into the fact the satyrs are likely horse/livestock/masculine inclined, eridan is a cold blood like the rest of the presumed satyr tags, and karkat has the usual Plot Relevant Character Boost.
Entry Items always corresponding to text colour is also probably something to stick with but it also seems to articulate itself after we get a better sense of what the characters is struggling with or has as an unstated character goal. Something vegetal or gardening based is a good place to start though.
I'm also dearly curious if her colour name is just a her thing and it patterns her after Rose especially, or it's a nymph wide affectation given their association with The Goddess Of Fate they obviously would venerate as prophesy obsessed as they are. Assuming CC is indeed a nymph her having a name like "Cl'ova" or "Pi'Nah" could solve that though.
If we meet the rest of the nymphs then the satyrs or rubber band back and forth is also something for what one presumes is this week's update.
